Yes, I may have been "lucky" in the sense that I probably already had the prerequisite libraries installed, and had perhaps already messed with the required settings. There seem to be two orthogonal components necessary to get smooth fullscreen video from youtube in firefox: "Accelerated web page rendering" and "Hardware accelerated video decoding". For what it's worth, I now get smooth fullscreen 1080p video from youtube with very little CPU load on a state of the art 14 year old CPU and mediocre Radeon RX 460 from 2016 on a 3084x1600 monitor, all on a standard debian stable gnome+wayland+firefox and free drivers (as far as I know!) so it's definitely doable without much tweaking other than having the right packages and maybe one or two settings in firefox.
